BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a temperature-uniforming plate, and more particularly to a temperature-uniforming plate that provides a supporting effect.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98

A conventional temperature-uniforming plate in accordance with the prior art shown in comprises a base plate and a cover plate respectively formed with a sidewall by stamping process. The base plate and the cover plate are separated to each other by the two sidewalls after being assembled. The structural strength of the conventional temperature-uniforming plate is strong enough to load a normal pressure when the conventional temperature-uniforming plate has a great volume and is made of thick metal sheet. However, the structure of the conventional temperature-uniforming plate may be weakened when the conventional temperature-uniforming plate is thinned and simplified.

In view of this, some manufacturers disposed capillary structures and supporting structure into the conventional temperature-uniforming plate. However, the flexural strength of the conventional temperature-uniforming plate is weakened and easily deformed due to a shearing force after being thinned.

The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional temperature-uniforming plates.

A cover plate is mounted onto the base plate. The cover plate is formed with a top surface and a bottom surface. A frame 30 is sandwiched between the inside surface of the base plate and the bottom surface of the cover plate. A vacuum chamber is defined among the inside surface of the base plate, the bottom surface of the cover plate and an interior of the frame, wherein the vacuum chamber is provided for containing coolant. At least one capillary structure and at least one supporting structure are disposed in the vacuum chamber, wherein the at least one supporting structure has two opposite ends respectively abutting against the inside surface of the base plate and the bottom surface of the cover plate.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-5, a temperature-uniforming plate in accordance with the present invention comprises a base plate 10 formed with a heat conducting surface 11 and a inside surface 12, wherein a contacting area 13 is formed on the heat conducting surface 11 and abutted a heat source 05. A cover plate 20 is mounted onto the base plate 10. The cover plate 20 is formed with a top surface 21 and a bottom surface 22. A frame 30 is sandwiched between the inside surface 11 of the base plate 10 and the bottom surface 22 of the cover plate 20. A vacuum chamber 40 is defined among the inside surface 11 of the base plate 10, the bottom surface 22 of the cover plate 20 and an interior of the frame 30, wherein the vacuum chamber 40 is provided for containing coolant. At least one capillary structure 41 and at least one supporting structure 42 are disposed in the vacuum chamber 40, wherein the at least one supporting structure 42 has two opposite ends respectively abutting against the inside surface 12 of the base plate 10 and the bottom surface 22 of the cover plate 20. Two arms 31 respectively extend from the interior of the frame 30 and correspond to each other, wherein each arm 31 has a distal end 32 separated from each other. The two arms 31 are sandwiched between the inside surface 12 of the base plate 10 and the bottom surface 22 of the cover plate 20. A passage 33 is defined between the two distal ends 32 of the two arms 31. The distal end 32 of each of the two arms 31 is situated within the contacting area 13.

With reference to FIG. 4, the heat conducting surface 11 of the base plate 10 abuts the heat source 05, such as a central processing unit such that the thermal energy from the heat source 05 heating the base plate 10 and the coolant in the vacuum chamber 40 is heated and vaporized. Consequently, the thermal energy from the heat source 05 is equally distributed to an inner periphery of the vacuum chamber 40 for providing an effect of temperature-uniforming. In the preferred embodiment of the present invention, the two arms 31 respectively extend from the interior of the frame 30 and correspond to each other, wherein each arm 31 has a distal end 32 separated from each other. In addition, the distal end 32 of each of the two arms 31 is situated within the contacting area 13 for providing a supporting effect to a weaken portion, corresponding to the contacting area 13, of the vacuum chamber 40. Consequently, the temperature-uniforming plate in accordance with the present invention can well load an external pressure during/after being assembled. As to manufacturing processes of the temperature-uniforming plate in accordance with the present invention, the frame 30 is formed with the two arms 31 by metal sheet stamping skill that is simple, quick and costs a low price and a purpose of thinning can be easily achieved. For example, the temperature-uniforming plate in accordance with the present invention has a good resistance to pressure and flexural strength even the frame is made of a thin metal sheet having a thickness of 1.5 mm.

With reference to FIG. 6 that shows a second embodiment of the temperature-uniforming plate in accordance with the present invention, in this embodiment, each arm 31B has a branch (not numbered) laterally extending therefrom and the distal end 32B is formed on a free end of the branch of each of the two arms 31B.

With reference to FIG. 5, the two distal ends 32 are aligned with each other. With reference to FIG. 6, the two distal ends 32B are staggered relative to each other. The shapes of the two distal ends 32B are different from each other.

With reference to FIG. 7, in this embodiment, the branch of each of the two arms 31C has a deputy passage 34 defined in a top thereof.

With reference to FIG. 8, in this embodiment, each arm 31 has an assembling hole 50, the base plate 10 has two assembling holes 50 defined therein and the cover plate 20 has two assembling holes 50 defined therein, wherein the assembling hole 50 in each of the two arms 31 aligns with a corresponding one of the two assembling holes 50 in the base plate 10 and the cover plate 20.

With reference to FIG. 9, in this embodiment, the base plate 10 has a sidewall 15 peripherally extending therefrom and the cover plate 20 has a sidewall wall 25 peripherally extending therefrom, wherein the two sidewalls 15/25 abutted each other after being assembled.

With reference to FIGS. 1-3, the frame 30 has a slot 35 defined therein. The slot 35 is provided for making a vacuum status in the vacuum chamber 40 and filling the coolant into the vacuum chamber 40, wherein the slot 35 is closed by filler 36 after filling the coolant into the vacuum chamber 40, as shown in FIG. 1.

With reference to FIG. 10, in this embodiment, the frame 30 has a through hole 37 laterally defined therein. The through hole 37 is provided for making a vacuum status in the vacuum chamber 40 and filling coolant into the vacuum chamber 40, wherein the through hole 37 is closed by filler (not shown) after filling the coolant into the vacuum chamber 40.

With reference to FIG. 11, in this embodiment, the cover plate 20 is formed with a raised portion such that a gap 38 is defined between the cover plate 20 and the frame 30. The gap 38 is provided for making a vacuum status in the vacuum chamber 40 and filling coolant into the vacuum chamber 40, wherein the gap 38 is closed by filler (not shown) after filling the coolant into the vacuum chamber 40.

The distal end 32 of each of the two arms 31 is situated within the contacting area 13 of the base plate 10 such that the temperature-uniforming plate in accordance with the present invention has a thinning and simplified structure for easily formed, reducing manufacturing cost and providing a supporting effect.
